SPECIFCATEON 'forming part of Letters Patent No: 314,614, dated March31, 1885.

Application tiled October 17, 1884. (No model.)

To all whom t may concern.-

Be it known'that I, NOAH SHAW, a citizen of the United States, residingat Eau Claire, in the county of Eau Claire and State of Visconsin, haveinvented a new and Improved Machine for Applying Babbitt-Metal Liningsto Bearing-Boxes, of which the following is a specification.

My improved machine for applying the liu ings, which will be hereinafterdescribed and specifically claimed, consists of different combinationsof mechanical parts, whereby different series of different-sizedbearing-boxes can be produced very accurately and expeditiously'withoutdanger from flaws, loss from waste of metal, and with less labor andexpense than heretofore, and the said combinations of parts being suchthat the halves of pillow-block or pedestal or other forms of dividedbearingboxes can be readily put in concentric position and clampedaround any desired sized core, with their Babbitt-metal space dividedinto two chambers; that interchangeable cores can be used, and thesecores centered and adjusted for properly receiving the melted Babbittmetal which forms the half-linings of the two halves of the box; andthat the finished halvesof the box can be quickly removed; and to effectthese objects it is only necessary to adjust a core-centeringcarriageplate in proper relation to a determined number of a scale;place a numbered core upon a centering device of this carriage, applythe lower half of a bearing-box against a vertical gage and clamp-plateof a table behindthe core and upon a packed flange of the core; placethe upper half of the bearing-box against the said lower half and uponthe said packed iiange and forward of a clamping-screw; placeproper-sized centering and dividing or parting plates in the rabbets ofthe j oint between the two halves of the bearing-box, thereby laterallycentering the bearing-box and dividing its Babbitt metal chamber intotwo parts; clamp the two parts of the bearing-box together and againstthe gage and clamp-plate of the table; introduce the melted Babbittmetal at one end of the bearing-box, and pour it into the spaces betweenthe core and the semi-cylindrical, or nearly so, surfaces of halves ofthe box; allow the metal to become solid;

unclamp and remove the upper halfofthe@ lbabbitted bearing-box, run backthe corecarriage andremove thelower halt' of the bab bitted box from thecore; continue this operation until a full complement of a given sizedbabbitted bearing-box is completed; remove the core, and substituteeither a smaller or larger core for aditferentsize or series ofbabbitted bearing-boxes, and repeat the operation just described until afull complement of this series and size is completed.

In the accompanying drawings, Figure 1 is a perspective view of thebabbitting-machine, showing also an ordinary divided bearing-box put inposition and ready for being filled with Babbitt metal. Fig. 2 is a topview of the saine, and Fig. 3 is a vertical transverse section of thesame.

The platform of .the machine is designated in the drawings by A, and itmay consist of an ordinary table, around the edge of the top a of whicha raised rim, a', may be provided in order to retain any casually-spiltBabbitt metal. On the top a, at the front side, au oblong rectangularextension is provided, and at the sides of said extension and across thetable rabbeted or dovetailed guides a2 are formed or applied', and onsaid extension and the top a, between the rabbeted guides a2, acarriageplate, B, is snugly fitted, so as to slide back and forwardthereon without lateral move-v ment. This carriage-plate is moved bymeans of a screw, C, which is provided with a handwheel, c, secured inan ordinary mannerjto a lug, b, of the carriage, and fitted into anutlug, a3, of the top a'ot' the table.

To the rear end ofthe plate B,l an upright y centering-pin, D, or othersuitable centeringA contrivance, is firmly attached, so asv to standopposite to and centrally between the ends of an upright gage andclamping-plate, E, whichis either fastened to Or forms a part of the topa of the table. be exactly vertical and parallel with Y each other,because in the operation of the machine the bottom surface ofthe lowerhalf, P', of a pedestal or other bearingfbox to be babbitted is made torest against said plate, while the pin D holds in position ametal gagedcentral core, F, aronndwhieh, excepting where certain centering anddividing or parting plates,A

The plate E and pin Dshould roo K, are applied, the melted Babbitt metalis poured after the other half, P, of the bearingbox and the centeringand dividing or parting plates are properly adjusted for this opera- Inpractice a sufficient number of acculately-turned or nicelygagedexchangeable metal cores F of different sizes are provided to suit thedifferent diameters of Babbitt linings for the bearing-boxes. The metalcore F rest-s on a collar, d, of the pin D, and is provided with a broadcollar, f, at its lower end, and with a porous or felt washer, f',resting on the collar f, as shown. In front of the pin D thecarriageplate B is provided with a sliding angular plate, G, which isplaced on top ofthe carriage-plate, and which, by means of a centrallongitudinal rib, g, on its under side and a central longitudinal slot,b, in the carriage-plate, is kept firmly in central position with thepin D, while by means of a bolt, g', passing through it and the slot bit can be moved toward or from the pin D any desired distance andfastened. The upright portion of the plate G is provided with an uprightslot, g", through which the reduced portion of a verticallyadjustablenut, H, is passed. Said nut has a head, h, at one side of the plate G,and an outer screw, h', at the other side of the same, upon which outerscrew a nut, h2, is fitted, and by this construction the nut can beraised or lowered in the slot g2, accordingly as the bearing to bebabbitted is long or short, and after the adjustment is made the head hcan be drawn tight against the plate G, for the purpose of retaining thethe nut H at the desired elevation. Into the nut H a screw, I, is1itted,which is provided wit-h a hand-wheel, t', at the outer end, and aclamp-disk, z, atthe inner end, to which the screw is swiveled. IViththe aid of this screw the top half, P, of a pillow or pedestalbearing-box is clamped in proper relation to the lower half, P', of saidbox on the rear side of the core F and its centeringpin D, as shown. Therabbeted fixed guides a2 of the table are marked with suitableindicating scales, J, while the plate B is provided with a pointer orindicator line, j.

The scale-line which serves for indicating the number or size of a givenbearing-box answers the position of the carriage-plate B pointed outbythe line j. Thus, when the indicator-line j on the carriage-plate Band the indicating-scale line (marked 3ft) on one of the guides a2 standin line, the pin D will then have been adjusted to its right positionfor receiving a core for forming a Babbitt lining in a bearing-boxadapted for receiving a shaft three and three-fourths inches indiameter, and in such case a core, F, three and three-fourths diameter,and marked 32, is placed on the pin D. Answering t0 different sizes ofbearingboxes to be babbitted, I providedifferent sizes of cores F andseveral different-sized pairs of centering and dividing or partingplates K. With each coreand pair of plates a full complement of aseriesof beari ings can be babbitted. The plates are hung on hooks 7c insertedinto the plate E beneath numbers conspicuously marked on the upper edgeof said plate, as shown in Fig. 2, the numbers on the plate Ecorresponding, respectively, to the numbers on the scalesJ and cores F.The plates of a pair are exactly alike in form and size, and a pair areused in connection with each-sized core. A plate is inserted in each ofthe rabbeted surfaces of the lower half of the bearing at the pointpbetween the two halves of the bearing, and these plates,beingrespectively of the required width, touch the core F and the corners ofthe rabbets, thereby centering the two halves tween the two halvesuofthe divided bearing, i

and insuring their being held in position centrally with the core, butout of contact withI it except where the parting plates touch the coreafter once being clamped; and while the' plates K center the bearing-boxlaterally, the gage and clamping-plate E, in conjunction with theclamping-screw I, secure the bearing in a central position with respectto the core, in a direction at right angles to the firstnamed position.

By means of the plates K the Babbitt metal for forming the lining in thelower and uppe'r halves of the bearing-block is divided into two parts,and therefore the halves of the bearingbox with the Babbitt lining inthem can be readily removed from the core when the Bab- The hooks k andbitt metal becomes solid. the numbers on the plate E, in conjunctionwith the scales J and numbers on the cores F,- att'ord great convenienceto the operator in the handling of the plates K, it only being necessaryfor him to look at the size of the core or the adjusted vposition of thesame on the scale, and then to take from the hooks two plat-es which areopposite numbers corresponding to the number of or to the adjustedposition of the core with respect to the number on the scale.

Vhen the machine is to be used, the desired size of the bearing isascertained, and a core, F, corresponding thereto is iitted on theceutering-pin D. The carriage-plate B is then moved by the screw C untilits indicator-line j stands in line with a number of the scale on one orthe other of the guides a2, corresponding with the number of thebearing-box. The lower half, B', of a bearing or box is now placedendwise upon the felt or other suitable packing-washerf ofthe core F,with its bottom p touching the plate E, and its semicircular top surfacea proper distance from the core, and then the upper half, P, of the boxis placed in like manner on the washer f of the said core F, with itssemicircular surface IIO a proper distance from the core, its positionbeing between the core and the clamp-screw I; and now the properdividing or parting plates K are placed into the rabbeted portions ofthe joint between thetwo halves of the box, with their inner edgestouching the core F, and then the screw is turned up until the twohalves of the bearing-box are firmly clamped against the dividing-platesand the gage and clamp plate E. The melted Babbitt metal is now pouredat one end of the box into the two semi-cylindrical spaces around thecore F, and by the felt washer it is prevented from leaking out below,and when it has become hard the screws of the carriage-plate B and ofthe plate G are turned back, and the babbitted bearing-box released, sothat the two halves thereof can be removed, being now in a finishedcondition. The described operation is repeated until any desired numberof a given size of bearing-box are babbitted or lined with Babbittmetal, and when the full complement is babbitted the core is removed andeither a smaller or larger one brought into use for the operation ofbabbitting a series of a differentsized bearing-box.

W'ith my invention a given number of bearing-boxes can be babbitted in amore perfect manner and in a much shorter time than is possible with theordinary modes, inasmuch as with such modes the adjustments of lthe coreare slowly made by hand, and the vdivided bearing-box is necessarilyprovided with end guards or rims, which require to be filed or turned tot the core, and between which and the core the melted Babbitt metalfrequently and wastefully as well as injurionsly leaks, causing unevenplaces and blow-holes in the Babbittlinings ofthebearing-boxes; andboxes lined by my machine will all be of standard size and ofthe samedepth from center to bottom of box, thus saving a great amount oftrouble in putting the boxes in position for use. This result is securedby means of the carriage plate and the scale J.

The machine will greatly reduce the cost of babbitting or fitting boxes,it having been found by experience that with the proper con. veniencefor melting the Babbitt metal forty or fifty boxes can be easily tted inan hour; and as the boxes are securely clamped in position by simply theclamp-screw I and plate E, and no extraneous bolts or clamps beingnecessary, rapid work in the babbitting operation is renderedpracticable. As the machine allows of the melted metal being poured inthat end of the box which is uppermost when clamped in the machine, bothspaces can be filled at the same time, and the metal by being thuspoured in forms more perfect linings than if put in in the ordinary way,and no matter how slightly fluid the Babbitt metal may be the spaceswill always be filled.

In the manufacture ofthe machine for useI propose to furnish, say,twenty-four corestwelve for cold-rclledshafting and twelve for turnedshafting. r[hose for the cold-rolled shafting as well as the others willbe of differ# ent or gradually-increasing diameters, and for liningboxes for turned as well as for coldrolled shafting a provision is madeby making the cores of a larger size or gage than the shafts they are tobe used with, so as to allow for shrinkage of the lining of the boxduring the cooling of the metal, and permit the shaft to turn freely ina newly-babbitted box,there by saving the expense of scraping or turningdown to the proper size, and also avoiding that destructive frictionexperienced from the use of babbitted boxes produced by the most commonmeans-viz.,by babbitting around the shaft. The result of the frictionmentioned is that many of the linings are melted before the shaft hasworn them to the proper size, causing delay and expense, which isavoided by having the cores of the proper size.

In the machine represented by the drawings the scale is adapted forboxes of three and threefourths inches; three -inch for turned shafting,and a three-inch for cold-rolled shafting, and also a two and ve-eighthsfor turned shafting, and all these will t the same pin D,

vided which are suited to the production of roo any and all sizes ofbearings, according to the requirements of different establishments.

I do not regard it absolutely essential, while it is preferable, thatthe pin D should extend up entirely through the core, for it might bepracticable to hold, center, and adjust the core on the carriage-plate Bby providing a socket or hole in the carriage-plate, and having anextension on the core below its flange, and setting and securing saidstem in the socket; or a short centeringboss might be provided in lieuof the pin D on the plate B, and the core tted and secured upon thesame.

The washer f may be made of any suitable soft, or ductile, orcompressible, packing material, but I prefer to make it of either wool,hair, or mineral felt; and by the use of such a washer, instead of hardmetal, or a clay or putty washer, a very tight packing is secured, anddanger from air-traps or blowholes avoided. The washer f might be placedupon the top of the carriage-plate, and the flange of the core might beleft off; but I prefer to have the flange formed on the core and thewasher applied upon it, as described.

It will be evident that if, for any reason, it should be deemeddesirable to construct the machine for lining only one size ofbearingbox, the core might be a xture with the carriage-plate, and suchmachine with fixed core, it is intended, shall be embraced as myinvention under this patent.

IIS

It might be practical to employ a longer table with a longer clamp-plateE, and to provide a broader core-carriage, and set a nu1nber ofcore-pins D for difierent-sized cores in a line upon this carriage, andto provide a number of separate clamping-screws I, and thus adapt themachine for lining a series of differentsized bearing-boxes at one time.

The gage-plate E might be made to move to or from the core, and the corekept stationary; or both the plate E and the core might be made to movetoward or from each other by appropriate mechanism, and theadjustableplate G might be made a part of or be bolted firmly to the movablecarriage B, but for convenience is better if constructed as shown.
